Had one in a sample pack. Plopped it into my Cadet Open Comb. The first shave irritated my face pretty badly. Having had blades get better the 2nd or 3rd shave I kept it in for a second time. BAD IDEA! Yeoooooooowwwwww! Grabbing, pulling, etc. Abysmally dismal. I love Supermax Platinum and Titanium. They can keep the SUPER STAINLESS.

I have had four shaves with a Supermax Sunrise in my Mergress now. The blades themselves are marked Supermax Super Stainless. I must say that I am totally impressed with these blades. They are sharp, smooth, and have given me nothing short of perfect shaves so far.
